The C Series brings KEF’s audio technology and ‘know how’ to affordable hi-fi loudspeakers. Both beautifully styled and incredibly versatile, the C Series perform as well as speakers twice their price.

KEF was founded on innovation and new technology. We are recognised in the history of loudspeaker development as one of the most important contributors and a great deal of our research has been published at well respected professional institutions, including the Audio Engineering Society and the Institute of Acoustics. KEF's research legacy includes contributions from some of the greatest and most respected loudspeaker designers of the last five decades. Today, KEF are the company to beat in computer analysis of loudspeakers. The software that we use to run our analyses is also used to power eighty-five percent of the world's supercomputers. We strive always to better understand the instruments that we design and manufacture.
